General
Colour	Red

The shrink tube Pliofine B-EX 3800 (1.22m) red from Ses-Sterling is a professional protective material for cables and wiring in electrical and IT installations. It serves for mechanical and electrical insulation as well as protection against environmental influences such as moisture, dust, or mechanical stress. The shrink tube is activated by heat and shrinks to approximately half its original diameter, creating a tight, dense covering. The red colour identifies it as a visually distinguishable element, which is advantageous in certain application areas, such as cable marking.

Applications
The shrink tube is suitable for use in industrial electrical installations, machine building, automation technology, and IT infrastructure. It is frequently used for insulating cables, sealing wiring, marking connections, or protecting connection points. The length of 1.22 metres allows processing of multiple cable sections or longer sections in a single work step. The red colour supports visual differentiation of wiring, especially in complex systems.

Functions and Features in Detail
The Pliofine B-EX 3800 shrink tube has a shrink ratio of 2:1, meaning it shrinks to approximately 50% of its original diameter. This ratio ensures a tight fit around the cables or wiring to be protected, creating a dense and mechanically stable covering. The material properties ensure good adhesion and shape stability after shrinking. The red colour is consistently distributed along the entire length of the tube and remains intact even after heat treatment.

Technology Explained Simply
The shrink tube is made of a thermoplastic material that changes shape when heated. When heat is applied — for example, using a hot air blower — the tube shrinks and conforms precisely to the shape of the underlying wiring. This process creates a tight, waterproof, and dustproof covering that protects cables from external influences. The shrink ratio of 2:1 is a standard value that allows sufficient fit accuracy for many cable diameters. The red colour serves as a visual identifier, which is beneficial in certain applications, such as identifying control wiring.

Compatibility and Accessories
The shrink tube is suitable for use with cables and wiring of various diameters, with the 2:1 shrink ratio enabling flexible adaptation. It can be processed using standard heat sources such as hot air blowers or dedicated shrink tools. Use in combination with other protective materials, such as cable protection conduits or insulating tape, is possible, provided material compatibility is ensured. The red colour enables easy visual differentiation, especially in systems with multiple wiring types.

Installation and Mounting
Installation is performed by sliding the shrink tube over the cables or wiring to be protected. It is then heated using a hot air blower or another suitable heat source until it fully shrinks. Care should be taken to ensure even heat distribution to avoid uneven shrinking or material damage. Processing is done at room temperature, with the heat source providing the required temperature to activate the shrinking process. The length of 1.22 metres allows processing of multiple sections in a single work step.

Operational Advantages
The shrink tube provides a durable, mechanically stable, and weather-resistant covering for cables and wiring. The red colour supports visual identification, simplifying maintenance and servicing. The 2:1 shrink ratio ensures a tight fit, enabling a dense seal. The material quality ensures long service life and high resistance to mechanical stress and environmental influences. Processing is simple and requires no additional tools beyond a heat source.
